Node feature discovery for Kubernetes
185b406ee7
Add internal API for the nfd-worker custom feature source rule configuration. This API has already diverged from the NFD NodeFeatureRule API in that annotations, extended resources or taints are not supported. This patch basically copies the Rule type (and it's sub-types) from the nfdv1alpha1 package. It also adds conversion functions from the internal rule API to the "external" nfdv1alpha1 API. This is done to use the same rule matching functionality (from the nfdv1alpha1 package). One notable remark is that the feature source rule config supports some custom formatting (short forms, multi-type fields) that relies on special json/yaml unmarshalling functions that are better to nuke from the nfdv1alpha1 package (in another patch). These (legacy) syntax specialities are most probably used by nobody but let's keep them as they're already there. Unit tests to cover the custom json unmarshalling are now added. |
